I was quite young at school. In those days, for one reason or another, I think connected with the war and connected because things hadn't settled down, it was very- then it was much easier than it is now, to get into Oxford or Cambridge. So, in 1944, when I must have been 16, I went to Oxford and said, this is what I wanted to do, come and be a student although not this year. And, Balliol said, no thank you. I think I was going in for a scholarship only, at that time. And, New College said, hello, it's you lot again, is it? Or words to that effect because my grandfather had been a fellow there and J.B.S had been there, and they weren't at all surprised to see me. And they said, yes, of course, you know, no difficulty with that. I remember my interview with them very well. They said, oh, you- I think it must have been a classics Don, because I was, you know, going on already, well, science was what interested me, but they also- I suppose an arts Don, I don't remember who it was who said, oh, you said something in your- You had to write these general essays. You had something in your essays about the Romans on their temples putting stone carvings which represented where the wood had been inserted- wooden pegs had been inserted, the temples were made of wood. Can you tell me more? And I said, no I can't possibly tell you more, I was just showing off about that.
